METHOD FOR DETERMINING PRESSURE |
摘要 |
A method of determining pressure requires that a three-dimensional surface o f an object (14) be covered with a pressure sensitive coating. Next a raw firs t image (74) is acquired while the object (14) is not under test and a raw second image (74) is acquired while the object is under test. The raw first image (74) and the raw second image (74) are adjusted for a dark image (76) to form an adjusted first image and an adjusted second image. The adjusted firs t image and the adjusted second image are mapped (78) from a two-dimensional representation onto a three-dimensional model, to form a first model and a second model. A ratio model is formed (80) by taking the ratio of the intensity of the first model and the second model. Finally, a pressure is determined (84) for every surface that forms the three-dimensional model.</S DOAB>
